As you proceed in the level you will find a machine that fires up a whirlpool underwater which can push X up to the surface of the water. The sixth heart is in Launch Octopus' stage. When you reach the highest one, as it reaches the top-left corner of its path, dash and jump to the left into the open air, and you will land on a large platform just above where the level started. At the start of the level you will climb up platforms which move on their own. The fifth heart is in Storm Eagle's stage. Once you destroy it, jump up the wall to find the heart.

To find the heart, you must destroy the bulldozer before it reaches the area where the heart is, otherwise it will destroy the wall and you won't be able to reach it. When you drop down a long shaft, you will land behind the large bulldozer-type enemy, who will charge forward and break down the rock walls in front of it until it falls into the spikes. The fourth heart is in Armored Armadillo's stage.

You can use the Boomerang Cutter to reach it, or if you jump off the wall using the boots and jumping from the right spot, you can jump around and grab on to the edge of the platform to reach the heart. As you come to a ladder in a corner which leads down to the rest of the level, if you jump up the wall you will see this heart sitting on a small ledge. The third heart is in Spark Mandrill's stage. Once you defeat Chill Penguin, the fire will disappear from this level and you will be able to walk underneath the platform and find the energy heart. You may have seen it as it is in clear view, but when the fire is still around you can't reach it. The second heart is in Flame Mammoth's stage. Go left, and using the Fire Wave weapon, destroy the second igloo-shaped building and the heart will reveal itself. Once out in the open, jump up to the platform above the area where you used the suit. When you reach a wall which the suit can't jump over, leave the suit and continue. As you proceed in the level, you will find an armored suit that X can use. The first heart can be found in Chill Penguin's stage after you have defeated Flame Mammoth. The body upgrades will allow X to become much stronger and able to perform special abilities.

Sub-Tanks will allow X to store energy to be used during battle if his energy is low. Energy hearts will allow X to hold more energy, making him stronger and able to survive longer in battle. The list includes the locations of the energy hearts in each levels, the four sub-tanks, the four body upgrades and the secret Fireball weapon. The item list shows where all the special items are to be found and how they can help out X.
